Glances Containers API Memory usage does not match Primary Output

Moving this to an issue as I have been able to recreate the bug on a separate environment.

Discussed in #3099

While working to setup integration between Glances and GetHomepage.dev, I have noticed an issue where the Glances API seems to report incorrect docker container memory usage, while the Glances primary output reports correct usage. Screenshot below showing Docker Stats matching with Glances output, while Glances API reports a massively higher number, 3GB in this example. Other containers captured in this example are also have similar dependencies.

I am running this on Ubuntu 24.04 with the ubuntu-latest-full version of Glances on Docker.
Glances 4.3.0.7 with psutil 6.1.1
